MEANS FOR LINE JUSTIFICATION Filed Aug. 28, 1954 '2 Sheets-Sheet 2 Patented Apr. 20, 1937 UNITED STATES PATENT OFFICE Application August 28,

4 Claims.

This invention relates to a method of line justification for typewritten matter, and photographic means for carrying such method into operation.

In the past when photo mechanical reproduction of typewritten data has been tried, line justification, that is, the proper spacing of the characters to make the length of all lines uniform, has been attained in many different ways, such as; manual spacing by the operator on the typewriter, typing on tape and. cutting to proper length and mounting, typing on stretchable paper, cutting into strips and mounting, etc. All these and other methods have been slow and require considerable time for preparation of the copy.

One of the objects of the present invention is to effect line justification of typewritten or the like matter, without the necessity of doing anything to the original record in the way of cutting, stretching, or the like.

Another object is to produce a device for photographic reproduction of typewritten or the like matter, having means for relatively adjusting the plate or film and the typed sheet, so as to compensate for the variation of line lengths on the sheet, and make all reproduced lines of even length.

Another object is to produce a device for effecting concomitant operation of the plate or film, and the work sheet.

Other objects will appear from the following detailed description, and appended claims. One form of device for carrying my invention into effect is illustrated in the accompanying drawings, in which:

Fig. 1 is a side elevation of a device for carrying my invention into practice.

Fig. 2 is a top plan view of the same.

Fig. 3 is a fragmentary detail perspective view of the copy holder, film, and the means for ad vancing the two concomitantly.

Fig. 4 is a detail perspective view of the copy holder and its mask. A

Fig. 5 isan enlarged fragmentary detail perspective view showing the copy holder and associated parts.

Like characters of reference refer to like parts in all views.

Referring to the drawings in detail, l0 represents the framework of the machine, which may be of any suitable construction to support the working parts of the machine. Mounted on the framework I0 is a camera II, the lens board being indicated at l2. The lens board I2 is 1934, Serial No. 741,798

(flDl. 88-24) secured to a rod [13 which extends across the machine, and near its ends rests in bifurcations in levers l4 pivoted at l5 to brackets l6 secured to the framework of the machine. Springs ll tend constantly to move the lens board toward the right in Fig. 1. The lower ends of levers i4 carry anti-friction rollers l8, which ride on the curved surfaces of cams l9 fixed to a shaft 20 having bearings in the machine framework.

Inside the camera is supported in any well known manner, a supply roll 2| (Fig.3) carrying photographic film, sensitized paper or the like indicated at 22. The film 22 is fed down in back of a mask 23, about a feed roll 24 to the receiving roll 25. Feed roll 24 is fixed on a shaft 26 which extends through the side of the camera, and carries a beveled gear 21 meshing with a gear 28 fixed to a stub shaft 29 having its bearing in a suitable bracket. Slidably mounted on the lower end of shaft 29 is a clutch member 30 which may be raised and lowered by a handle 3! (Fig. 1).

Fixed to the machine frame, and arranged angularly with respect to the camera ll, are slotted rails 32 (Fig. 2), in which brackets 33 are arranged to ride. Carried by brackets 33 is a frame 34 which carries a removable mask 35. The aperture in this mask is large enough to expose only one line of typewriting at a time. The right hand end of this aperture may be provided with a scale indicating letter-spaces. The armature of this mask is in optical alignment with the aperture in mask 23. Slidably supported in the frame 34 is a copy-holder formed of a back portion 36 to which are hinged side flaps or clamping strips 37. Portions of soft rubber or felt are shown at 38 as set into the face of member 36 to co-act with strips 31 for gripping the paper 3].

Fastened to the lower edge of the copy-holder and extending downwardly therefrom is a rack bar 39, the teeth of which mesh with a long pinion 40 fast on a shaft 4| having bearings in the main frame, or in brackets attached thereto. Fast on shaft 4| is a bevel gear 42 which is in mesh with a gear 43 fast on a stub shaft 44 in axial alignment with stub shaft 29. Fixed on the upper end of stub shaft 44 is a clutch member 45. Shaft 4| is disposed parallel with the angular edges of rails 32.

Pivotally attached to brackets 33 are respective links or push rods 46, the opposite ends of rods 46 being pivotally connected to a U shaped frame 41 having its legs pivotally secured to the main framework. Secured to the middle of frame 41 is a handle 48 by which the frame may be conveniently rotated about its pivots. Fixed to one leg of frame 41 is an indicator 4!! which traverses a scale plate 50, the graduatfons on the mask 35. A link 5| connects frame 41 to a cam I9 (Fig.1).

The method of justifying is as follows2-Successive photographs of successive lines of type- 10 writing are made the distance between the copy and the sensitive plate, being varied according to the length of the typewritten line, so as to make all photographic lines of equal length, the lefthand letter of the copy being arranged to always fall on the same vertical line of the plate.

The means above described for carrying this method into effect operates as followsz-First, the film 22 is placed in the camera. Then the copyholder 3631 is raised, the clutch 30 being disconected. The sheet to be copied is placed against portion 36 and clamped there by strips 31.

The copy-holder is lowered until the first line of the typewriting is visible through the opening in mask 35. The frame 34 is moved to the right or left in Fig. 1, according to the reading of the last letter of the line on the scale on mask 35. This movement is accomplished by movement of handle 48, the amount of movement being indicated by moving indicator 49 over scale 50 until it corresponds with the reading of the scale on mask 35. The angle of rails 32 is such as to keep the left hand letter space of the copy always in the same vertical line of photographic reproduction on the film or plate 22. The movement of frame 41 35 causes link 5| to effect movement of cams I!) so as to move the lens board |2 accordingly, the contour of cams |9 being such as to give the correct focus. Lever 3| is now shifted so as to clutch members 30 and 45.

is now taken. The copy is now raised to expose line 2. During this operation rack 39 turns pinion 40 and shaft 4|, which causes gear 42 to turn gear 43, and, as shafts 44 and 29 are clutched together, causes gear 28 to turn gear 21, whereby 45 the film or plate 22 is advanced one line space.

, The reading on the scale at the aperture in mask 35 is again taken, handle 48 is moved until indicator 49 is in a corresponding position on scale 50, and the next photograph is taken, etc.

50 It is, of course, understood that the camera, or parts of it, could be moved instead of the copy, and that the device if stood on its side would bring the left-hand side of the copy always in the same horizontal (instead of vertical) plane on the film or plate. It will, of course, be understood that 22 represents any sort of photographic material, Whether it be film, paper, plate, or what not.

While I have described what I consider to be a highly desirable embodiment of my invention, it

is obvious that many changes in form could be made without departing from the spirit of my on which are arranged to correspond with those The photograph of line I I invention, and I, therefore, do not limit myself to the exact form herein shown and described, nor to anything less than the whole of my invention as hereinbefore set forth, and as hereinafter claimed.
